Elder Wood
The Ravenclaw's Diadem, one of the nine Deathly Hallows, is already Scabbers.
It did not demonstrate the ability to increase wisdom as the legends had suggested.
Nicolas had undergone examinations and concluded that:
Ravenclaw used Prehistoric Mysteries related to time to deliberately subject the Diadem to the ravages of ten thousand years.
The purpose is unclear... but the Diadem is now ruined.
Of course, over the course of thousands of years, the Diadem has only rusted, which also highlights its extraordinary nature.
But no matter how extraordinary it is, it's still just a piece of junk... If you sell it as scrap, besides Voldemort, probably no one else would want it.
What William wanted was a flawless Diadem.
Even if you're smart enough, who wouldn't want to grow even wiser?
Moreover, the Ravenclaw's Diadem and the Bronze Ring are a perfect match.
However, repairing it is by no means an easy task.
The safest method is definitely to unlock Nicolas's Book of Alchemy, which contains the steps to repair the Deathly Hallows.
However, this method requires finding Slytherin's Wand, but Little Tom is still in Ilvermorny, waiting for the "flower to bloom".
I wonder when that will happen.
The second approach is to fight time with time.
Since Ravenclaw has shifted the timeline of the Diadem forward, we can simply use the power of time to reverse it.
William doesn't possess the Prehistoric Mysteries, but the Department of Mysteries does.
The clocks in this room all embody the power of time.
Most importantly, he can guide this power and apply it to the Diadem.
Of course, we must also mention Tywin, William's former best Defence Against Dark Magic teacher.
Back then, Professor Tywin stole several Time-Turner from the Ministry of Magic.
Although he played with time, killed himself, and became the ultimate wage slave, allowing William to successfully take over... he did actually obtain the Ravenclaw Bronze Ring.
I highly recommend this app; it's really great and worth installing for all book lovers. It supports both Android and Apple phones!
Tywin's method was to use the Dark Magic from the Three Books of Occult Philosophy to channel the power of the Time-Turner into the door knocker.
At the time, William found the spellbook in the Defense Against the Dark Arts Office and copied its contents using Doubling Charm.
This book, written by the dark wizard Heinrich Agrippa, contains a large amount of magic.
Over the years, William has studied this very deeply, which is why he dares to repair the Diadem in this way.
William, after drinking Felix Felicis, suddenly opened his eyes, a feeling of immense exhilaration flowing through his body.
He felt he could do anything... repairing the Diadem would be a piece of cake.
William took out his wand and placed the Diadem on the ground.
However, a sacrifice is needed before we can begin.
Back then, Tywin killed Prefect Robert and used his life as a blood sacrifice.
William has found a fine offering, right here in this room.
He turned his head to look at Luna and smiled at her.
Those eight teeth shimmered with glaze in the air, appearing exceptionally white.
That's right, the sacrifice is Luna... Of course, that's impossible!
William would never do such a thing; he simply wanted to remind the girl.
"Luna, this room is going to be dangerous. Go find Cedric and the others first."
Also, drinking the rest of the Felix Felicis will make you much safer.
Luna reluctantly looked away from the Diadem, hummed in agreement, then turned to William and said seriously, "Be careful."
After Luna left, William called out to the void, "Fawkes, don't be shy, come out and play!"
William called out several times before a song suddenly began, and Fawkes appeared out of thin air.
It flapped its wings, circled for a while, and finally stopped, hooking its claws around William's shoulders.
It stared at William, its eyes darting around, as if it wanted to peck him.
However, since Fawkes has agreed to come out, it has clearly accepted its fate as a "tool bird".
That's right, Fawkes was the sacrifice.
Fawkes immense magical power, capable of infinite resurrection... making him the perfect choice for a sacrifice.
It works better than any wizard.
Therefore, Fawkes once again proved with its actions:
There's a reason why every wizard wants to own a phoenix.
When you want to leave, the phoenix can appear in places where the wizard cannot Apparition;
When you're trapped in Chamber of Secrets and have no food, the phoenix can provide an endless supply of "chicken legs," making it practically a perpetual motion machine.
Its flames are also very powerful, and it can also provide a "blessing" buff.
Fawkes... forever a legend!
Of course, getting Fawkes to agree to do this kind of work wasn't so simple.
William will definitely have to go through Dumbledore's back door.
They also had to sign a series of humiliating agreements with Fawkes, such as... providing the best food.
But this guy, having nothing better to do, eats African Tree Snake as snacks.
Tree snake skin is an ingredient in Polyjuice Potion, and it's quite expensive... Who can afford to raise such a wasteful creature?
It's even Trelawney- like than Bobocha.
William had to beg and plead before he agreed to use the flesh of the Acromantula as a snack substitute.
(Aragog: Meow meow meow?)
The offerings are ready.
William, holding Fawkes in one hand, stood in the middle of the house, raised his wand, and loudly chanted a spell.
After the sound stopped, William pointed his wand at Fawkes, and it began to bleed.
Golden blood flowed into a pre-placed metal cup, and a chill suddenly ran through the air.
William's entire body was filled with magic, and he murmured to himself:
"May the omnipotent darkness aid me, making this blood as potent as I desire."
Only blood can separate light from darkness.
Fawkes suddenly burst into flames, soaring into the air, its body ablaze, spewing forth a spectacular display of fire.
The blood in the bowl, like water droplets, all floated up and slowly fell into William's hand.
In an instant, not only did lightning flash between his fingers, but his entire arm was also enveloped in dazzling golden light.
William's sleeves fluttered slightly without any wind, and he twisted his body, his wand swinging with the movement.
Many clocks crashed together, the sound of them shattering echoing in the air.
William his head, his eyes blazing, and he held his wand high, unleashing an immense power of time that flowed through the air.
That immense power, like the Milky Way, crashed wildly against the clock.
The hummingbird, which had been in a cycle for who knows how many years, finally broke free of its restraints and hovered low in the sky.
But it inadvertently crashed into that air wall and was immediately torn apart and shattered beyond recognition.
Fawkes, who was reborn as a fledgling after death, also encountered this force.
But it discovered that it was not dead; instead, its wings began to grow fuller and its body gradually grew larger.
It "grew up" again in an instant.
William's entire focus was on manipulating this force.
His robes billowed, making him appear like a demon god, and he twirled his wand, aiming it at the Ravenclaw's Diadem.
That immense force then flowed downwards and struck the Diadem.
The Diadem, like a whale swallowing the sea, devoured all of time.
But it remained completely unchanged.
In some mysterious way, Felix Felicis directly told William that there wasn't enough time.
William raised his wand, and the entire room exploded. Almost all the clocks, including the Time-Turner, shattered and flowed toward the Diadem.
After an unknown amount of time, thick smoke began to rise, and the chanting gradually subsided.
William recently smiled and told him directly that he had succeeded.
He opened his eyes, glanced at the ground, and his smile suddenly froze.
The Diadem disappeared, and all that remained on the ground was... a branch of Elder Wood with white flowers blooming.
William succeeded, but he also failed.
Or rather,
He overreacted.
